This dataset contains information for 57,268 daily
occurrences of seventeen types of political events: riots, deaths from
political violence, political assassinations, armed attacks, elections,
protest demonstrations, regime support demonstrations, political
strikes, renewals of power, unsuccessful executive transfers,
unsuccessful irregular transfers, irregular power transfers, executive
adjustments, regular executive transfers, executions, acts of negative
sanctions, and acts of relaxation of political restrictions. The data
are recorded at daily intervals for each event group for each country
during the twenty-year period 1948-1967. For example, two riots in a
country on the same day appear as one record or case, but one riot and
one election in a country on the same day appear as two separate
records. Seven sources were used including THE NEW YORK TIMES INDEX and
the Associated Press.
